Leading the second wave of drones into battle is the Secondary Instance command.
The command drones most often seen leading a Virai combat group are the Secondary Instance architectors. The First Instance delegates distinct responsibilities to a number of secondary instances such as mining, scavenging, defense, invasion, construction or manufacturing, and then leaves each secondary to construct the tertiary’s and other drones it needs.
To manage the inherent weakness of the Virai drone categories, a number of secondary instance architectors are required in each force to provide command and control as well as to provide auxiliary services such as field repairs.
